THERE HAS BEEN a lot of conflicting info coming out about AMD, quad cores and its 65 nanometre process. To clear this all up, I dug up the info the old fashioned way, I asked AMD. So, directly from the horse's mouth, here is the info on all the hot AMD topics.

The QC parts are rumoured to be coming in Q2/07, Q4/07 and Q1/08, and are said to be both the old and the new cores. Some people call the Q2 part K8L, others call the Q4/Q1 parts the same, but since AMD has no product called K8L, that is kind of speculative.
